The use of both bioglass (BG) and β tricalcium phosphate (β-TCP) for bone replacement applications has been studied extensively due to the materials’ high biocompatibility and ability to resorb when implanted in the body. 3D printing has been explored as a fast and versatile technique for the fabrication of porous bone scaffolds. This project investigates the effects of using different combinations of a composite BG and β-TCP powder for 3D printing of porous bone scaffolds. Porous 3D powder printed bone scaffolds of BG, β-TCP, 50/50 BG/β-TCP and 70/30 BG/β-TCP compositions were subject to a variety of characterization and biocompatibility tests. The porosity characteristics, surface roughness, mechanical strength, viability for cell proliferation, material cytotoxicity and in vitro bioactivity were assessed. The results show that the scaffolds can support osteoblast-like MG-63 cells growth both on the surface of and within the scaffold material and do not show alarming cytotoxicity; the porosity and surface characteristics of the scaffolds are appropriate. Of the two tested composite materials, the 70/30 BG/β-TCP scaffold proved to be superior in terms of biocompatibility and mechanical strength. The mechanical strength of the scaffolds makes them unsuitable for load bearing applications. However, they can be useful for other applications such as bone fillers.

The Mississippi Delta represents one of the greatest concentrations of rural persistent poverty in the United States. High unemployment, high food insecurity, higher rates of obesity and diabetes, and low access to healthy, affordable food characterize much of the 18 counties in the region. In the face of this, The Good Food Revolution, a community-based program to address food related health and thereby employment, developed in response to significant need in three small communities in North Bolivar County, Mississippi, bringing together community members, public and private sector organizations, researchers and students. This paper examines the process of community-engaged scholarship from the theoretical lens on building community capacity and resiliency developed by Chaskin. Increasing community capacity for all participants in the Good Food Revolution project through community-engaged scholarship has built resilient communities that are engaging more communities.
